Synthesis of congeners and prodrugs. 3. Water-soluble prodrugs of taxol with potent antitumor activity

TL;DR: Observations suggested that esters at C-2' and/or C-7, which would tend to promote water solubility, might serve as useful prodrugs of taxol, and salts had improved antitumor activity as compared to the free acids.
Journal ArticleDOI

Cuticular hydrocarbons ofReticulitermes virginicus (Banks) and their role as potential species- and caste-recognition cues.

TL;DR: A bioassay was developed to test the species-recognition hypothesis and the experimental results supporting the hypothesis suggest that cuticular hydrocarbons might serve as species- and caste- Recognition cues.
Journal ArticleDOI

Supercritical extraction of taxol from the bark of Taxus brevifolia

TL;DR: In this article, the extraction of taxol from the ground bark of Taxus brevifolia using supercritical carbon dioxide and carbon dioxide + ethanol mixtures was studied and the extractions were preformed at 318 K and at pressures ranging from 18.07 to 25.79 MPa.
Journal ArticleDOI

Synthesis of pyrrolizidine alkaloids indicine, intermedine, lycopsamine, and analogues and their N-oxides. Potential antitumor agents.

TL;DR: In this paper, (+)-trachelanthic and (+)-viridifloric acids were synthesized and their isopropylidene derivatives were regiospecifically coupled, at C-9, with (-)-retronecine obtained by hydrolysis of monocrotaline, isolated from Crotalaria spectabilis.
